. into the bowl of the pipe.

4 Claims.

My invention relates to a smoking pipe so constructed 'that accumulations of the products of Acombustion which may be condensed and made up of nicotine, moisture or the like, as well as dust and slugs in the bowl of the pipe, are entrapped and prevented from passing into the mouthpiece and through to ythe mouth of the smoker. It is also designed to prevent the iiow of saliva or moisture from the mouthpiece back The pipe is particularly designed to providea cool, clean and refreshingsmoke without burning the tongue or mouth.` f

'Ihe invention has among its objects the production of a device of the. kind described for the purposes set forth, whichis efficient, compact, attractive and easily kept in a clean and sweetened condition. It has among its further objects the production cfa pipe that will efficiently cool the smoke, remove moisture and filter out the undesirable products of combustion.

'I'he same has asa further object the production of a pipe of the kind described in which iiltering elements may, in an emergency, be read- A ily made from the ordinary pipe cleaner which usually consists of .wire having bristles or fibers thereon, which cleaners serve as the filtering mediums. These cleaners are already on the market and may be procured almost any place.

The invention has as a further object a pipe of the kind described in which the pipe bowl and stem will not take. up and absorb moisture or oils, so that thel bowl of the pipe is always sweet, and in smoking, a pleasing aroma is secured from the tobacco without the odors of burning oil, slugs and the like usually found in carelessly kept pipes. r

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given. l

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawing, wherein like referencecharacters indicate like or corresponding parts:

Fig. 1 is a longitudinal section through a pipe showing one embodiment of my invention;

Fig. 2 is a View in elevation of the filter container removed from the pipe;

Fig. 3 is a sectional view taken substantially on the line 3 3 of Fig. 1; and

Fig. 4 is Vanother embodiment of the invention (Cl.y ISI-,12)

Referring to the drawing, particularly Figs. 1, 2 and 3, I represents a pipe bowl provided with the usual tubular stem 2 to which is attached the mouthpiece 3. The bowl and stem may be of any suitable material, wood, meerschaum, clay or 5 if like materials which are ordinarily employed, while the mouthpiece may be made of amberj Bakelite, hard rubberen any other material or combination of materials which are found satisfactory. Thebowl I is shown provided with the usual cavity, recess or chamber 4 which communicates through a bore or passageway 5 with the interior of the stem. The mouthpiece may be secured to the pipe stem in any satisfactory manner. As shown, the same is provided with a part 6 adapted to extend into the pipe stem chamber and has a bore extending through thesame from end to end. As illustrated, the bore in the mouthpiece is indicatedat l, the inner end of the same being branched as shown at 8 and 9, the branch 8 being slightly larger than the bore 'I with the branch 9 opening therefrom and constructed as at I0 to receive an insert, as will be more fully described hereinafter.

Interposed between the bowl and the mouth- 25,

piece is a iilter or absorbing member II preferably of spiral form to provide a circuitous passage for the smoke, and also an absorbing member I2, these being arranged in a tubular or chambered member consisting of the part I3 of Bakelite or equivalent material and an associated part 28 which may be of metal and forms a chamber for the reception of the absorbing member I2. The Bakelite member I3 is provided with a chamber I i therein and carries a tubular part I5 arranged to extend through the bore 5 into the bowl of the pipe, providing communication between the bowl and the chamber M.. Preferably carried bythe mouthpiece 3 is an element I8 having an extending part I9 which extends into the bore 3 of the mouthpiece and is carried therein. As shown, the end I 8 ts the bore or chamber I4 and if desired a gasket 20 may be provided which will closely fit the bore I4 and prevent leakage of moisture as well as provide for frictionally securing the .part I3 on the mouthpiece.

As will be noted by reference to Fig. 1, the passage 2l in the element I8 is preferably slightly angular so as to provide a substantial trap at 22 0 so that should there be any moisture in the bore or chamber I4 it will be prevented from passing into the mouthpiece. The opposite end of element I8 also forms substantially a trap 23, preventing any moisture or saliva failing to be trapped in the branch passage 9 from passing into the chamber I4.

An element 25 is also arranged in the mouthpiecewith the end 25 projecting back and provided with an opening El registering with the branch passage 9 oi the mouthpiece. The filter or absorbing element i2 is arranged in the construction shown in a tube member 28, the forward end of which extends up to adjacent the inner end of the member i3 and communicates with the chamber ifi therein. The mouthpiece end 30 is arranged to extend into and closely iit the bore of the element 25. The pipe cleaner I2 or the equivalent is positioned in the part 2! and pushed in suiiciently so that the forward end 3i reaches the chamber III so that any moisture entering from the bowl is drawn into the member I2 by capillary attraction. The opposite end of filter i2 is extended, as shown, at 32 past the branch passage 9 so that the moisture discharged through the branch passage will be absorbed.

To clean the pipe the mouthpiece is separated from the pipe bowl and stem by pulling it out, carrying with it members 28 and I3, as well as the projecting part I5. The parts 28 and i3 may then be separated from the mouthpiece by pulling the two apart, after which the filters or absorbing members may be replaced and the same cleaned in the usual manner with a pipe cleaner or swab.

As will be readily apparent from the preceding description, products of condensation, dust, dirt, slugs or other undesirable products entering from the bowl through the part I5 Will be co1- lected by the elements II and I2 without impeding the passage of the smoke through the device and out through the mouthpiece. Ordinarily oils are collected from the smoke by the filtering member II, while water and oils are drawn into member I2 by gravity and capillary attraction. The smoke in passing through is cooled and comes out of the mouthpiece with a fragrance and aroma. The moisture or saliva entering the mouthpiece and passing toward the bowl is discharged through the branch passage 9 and absorbed by the member I2.

The simplified construction shown in Fig. 4 operates in substantially like manner as the structure shown in Figs. l, 2 and 3 and is as readily cleaned. Referring to this figure, 35 represents the bowl of the pipe having the usual stem 35 terminating in a mouthpiece 3l, the two being secured together by frictional engagement of the extending part 38 on the mouthpiece engaging with the enlarged bore of the stem. The bore t9 of the mouthpiece is branched as shown at d@ and iii, the same being constructed so that there is substantially a trap i2 corresponding to the trap ZZ in the previously described construction. Within the bore 43 o the stem is arranged the filtering element 4t. The stern is also provided with an associated chamber IVI which communicates with the passage 4I in the mouthpiece and with the chamber 43 through the opening 48. This construction is also intended to provide a metal sleeve i4 extending through port 55. It will be noted that in this construction a trap is is substantially formed at the bowl end of the chamber 43. Within the chamber 4l is the absorbing member 50 arranged to absorb moisture from the mouthpiece at one end and from the chamber 43 at the bowl end.

Having thus described my invention, it is obvious that various immaterial modications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
